Bariatric surgery and diabetes: Current challenges and perspectives.

Diabetes mellitus (DM) and obesity have become public issues of global concern. Bariatric surgery for the treatment of obesity combined with type 2 DM has been shown to be a safe and effective approach; however, there are limited studies that have systematically addressed the challenges of surgical treatment of obesity combined with DM. In this review, we summarize and answer the most pressing questions in the field of surgical treatment of obesity-associated DM.

Breastfeeding vs. breast milk transmission during COVID-19 pandemic, which is more important?

The catastrophic coronavirus disease 2019 (COVID-19) pandemic has raised many health questions, and whether breast milk from SARS-CoV-2 infected mothers may be a vector for SARS-CoV-2 transmission has become a hot topic of concern worldwide. Currently, there are extremely limited and conflicting data on the risk of infection in infants through breastfeeding. For this reason, we investigated almost all current clinical studies and systematically analyzed the presence of SARS-CoV-2 and antibodies in the breast milk of mothers infected with SARS-CoV-2, their effects on newborns, and the mechanisms involved.

A novel indolylbenzoquinone compound HL-J6 suppresses biofilm formation and α-toxin secretion in methicillin-resistant Staphylococcus aureus.

Eradication of methicillin-resistant Staphylococcus aureus (MRSA) is challenging due to multi-drug resistance of strains and biofilm formation, the latter of which is an important barrier to the penetration of antibiotics and host defences. As such, there is an urgent need to discover and develop novel agents to fight MRSA-associated infection. In this study, HL-J6, a novel indolylbenzoquinone compound, was shown to inhibit S.

Transcriptional regulations of pollen tube reception are associated with the fertility of the ginger species .

and are economically valuable species in the genus . While is sexually active, adopts clonal propagation, although it has the potential for sexual reproduction. It is unclear so far at which step during the sexual reproduction of inhibition occurs, and what are the regulatory mechanisms underlying this inhibition.

Transposable elements activation triggers necroptosis in mouse embryonic stem cells.

Deficiency of the histone H3K9 methyltransferase SETDB1 induces RIPK3-dependent necroptosis in mouse embryonic stem cells (mESCs). However, how necroptosis pathway is activated in this process remains elusive. Here we report that the reactivation of transposable elements (TEs) upon SETDB1 knockout is responsible for the RIPK3 regulation through both cis and trans mechanisms.

[Effects of Germanium Concentrations on Germanium Accumulation and Biotransformation of Polysaccarified Germanium in Cordyceps militaris].

Objective: To study the effects of Germanium (Ge) concentration on Ge accumulation and biotransformation of polysaccarified Ge (PG) in Cordyceps militaris.

Methods: Solid and liquid culture were used in this study.

Results: In the solid culture conditions, when the Ge concentration of medium was 200 mg/L, the sporophore biomass of Cordyceps militaris was the maximum; and when Ge concentration was 300 mg/L,the amount of biotransformation of PG in sporophore was the highest; and when the Ge concentration is 250 mg/L, conversion rate of organic germanium (OG) in sporophore reached the highest value.

MicroRNA-200a inhibits epithelial-mesenchymal transition in human hepatocellular carcinoma cell line.

Objective: Our study investigated the role of microRNA (miR)-200a and its molecular targets in hepatocellular carcinoma (HCC) cells.

Methods: An inhibitor of miR-200a was transiently transfected into the hepatocellular carcinoma cell line, MHCC-97L. The effect of this transfection on mRNA levels of epithelial-mesenchymal transition (EMT)-related genes was measured by fluorescence-based quantitative real-time polymerase chain reaction (qRT-PCR).

[Study on monosaccharide composition of intracellular polysacchride and contents of cordycepin and cordyceps polysacchride produced by Cordyceps militaris induced by blue light].

Objective: To study effects of blue light irradiation on monosaccharide composition of intracellular polysacchride and contents of cordycepin and cordyceps polysacchride of mycelium and sporocarp in Cordyceps militaris.

Methods: The monosaccharide composition of intracellular polysacchride of mycelium and sporocarp in Cordyceps militaris as materials were determined by gas chromatography after 144 h blue light irradiation. The contents of cordycepin and cordyceps polysacchride of mycelium and sporocarp in Cordyceps militaris were detected at different blue light irradiation periods.
